Grammar Checker

Checking is free — creating an account takes seconds and doesn't need a card. Once you're in, paste your text and check as much of it as you like; that same account also unlocks the full findings list, fixes, and your verification report.

Paste the finished draft in above and run the check. You'll see every grammar mistake with a fix and a plain-language reason it matters — the same pass a careful reviewer runs before anything else. When you're ready, run the Full Check on the same document for plagiarism, AI detection, and readability too.

Paste the whole essay, not just a paragraph — grammar mistakes often cluster near transitions and citations, so the full document gives the most accurate pass. Fix what's flagged, then re-check before you submit. If the essay also needs a plagiarism or AI-detection pass, run the Full Check on the same document once grammar is clean.

Honestly, grammar alone rarely gets a paper rejected outright — but it's usually the first thing a reviewer notices, and it erodes their trust in everything that follows before the content is even judged. Subject-verb agreement, confused words, and punctuation around citations are the mistakes reviewers flag most often.

No hard limit on checking itself — free accounts include 1,500 verification words to start, so you can check as much as you like without word-count anxiety.

Keep it — it helps you write. TextWiser checks whether the finished document is ready to send. Different moment, different job.
